The version control module 810 is configured to reduce the workload of labeling, wherein manual labeling for each iteration is corrected based on pre-labeling of a classifier trained using all labeled data as training data; the method is characterized in that training data and a classifier are not available at first, labeling can be carried out only from the beginning (called as labeling round 0), the labeling result is set as 'labeling v = 0', the version numbers of classifier training, testing and pre-labeling on the basis are all 1 version, and each version needs to be stored by a separate storage space; starting from the first round of labeling, the labeling result includes the labeling result copy of the 0 th round, so that repeated labeling is avoided; meanwhile, the marking work only needs to be corrected on the basis of the prediction result (pre-marking) of the newly trained first-round depth network, so that the marking efficiency is gradually improved; the marked data can be rapidly increased along with the accumulation of the marked data and the improvement of the prediction accuracy of the depth network, after the nth round of marking, the marked result covers all the data to be marked, the depth network trained in the (n + 1) th round is an automatic identification system which is finally needed, and the test result of the (n + 1) th round is finally output; it should be noted that not all data from each round of labeling is trained in the DNN (DNN represents one of the detection, segmentation and recognition networks), and about 20% of the data is separated out to be left as a validation set in order to test the "health" of the current DNN.

The pre-labeling module 820 is mainly used for testing the current data set by using the detection, segmentation and recognition model trained by the previous version so as to perform pre-labeling work on the labeling work of the current version and reduce the workload of manpower. The detection labeling panel 920 performs detection, segmentation (or filtering), recognition, and layout analysis step by step to finally output the detection, recognition, and other results of the image to be tested (or to be pre-labeled), but the main purpose of this module is to provide prior information for labeling work, so that the result is taken out separately.

FIG. 10 is a diagram illustrating a pre-labeling effect according to another embodiment of the present invention.

As shown in fig. 10, after the "test/inference" button is clicked on the input image, the current image is subjected to a plurality of stages of cascade processing, and information storage, display and output are performed on the detection result (black typewriting shown in the image label display area 990), the segmentation result (a black and gray area shown in the image label display area 990), the recognition result corresponding to the detection result, the white text located at the lower right corner of the detection result in the image label display area 990, and the layout analysis result (text sequence is indicated by a white vertical line and used for indicating text sequence); and finally, displaying the information extraction result in the left text interaction area in line and sequence.

The labeling module 830 includes a detection labeling sub-module, a segmentation labeling sub-module, and an identification labeling sub-module.

FIG. 11 is a schematic diagram of a GUI of a sub-module for detecting annotation according to another embodiment of the present invention.

The detection labeling sub-module is located in the "detection frame manual correction" button of the "detection" panel at the manual labeling function module of the GUI shown in fig. 10. As shown in fig. 11, which is an exemplary diagram of manual labeling of a text box in a GUI, for distinction, the current labeling result is not enclosed by a dashed box, i.e. the "scroll" word (the last line of the 5 th column from right to left) in the image label display area 990, and at the same time, the image label display area 990 can display the result just labeled, the earlier labeled result is the text enclosed by the dashed box, for example, all the text in the second column from right to left is the earlier labeled result. After the 1 st round of labeling, manual automatic correction can be performed on the results of the machine automatic labeling, in the basic manner: and clicking a detection frame marking button, loading and displaying a pre-detection result while the system loads the current picture, and adjusting an inaccurate detection frame by a mouse.

The segmentation labeling submodule is different from the segmentation of the text at the pixel level, and the segmentation is referred to as the pixel level segmentation of the detection box, namely, the pixel-by-pixel regression inside the detection box is used as the text confidence of the current detection box, so that the detection result can be filtered. Therefore, the standard image of the segmentation label can be generated by directly imaging the label of the detection frame. However, in consideration of the application of a specific scene, for example, incomplete characters at the edge of an image do not need to be detected, the detection can be realized by adding or deleting the marks of the detection frame in the step of dividing the marks.

FIG. 12 is a schematic diagram of a graphical user interface of a segmentation annotation sub-module according to another embodiment of the present invention.

On the GUI shown in fig. 9, the current image can be segmented and labeled by clicking the "segmentation manual correction" button, as shown in fig. 12, the current image and the result of detecting the label are loaded first, then add/delete is performed on the basis, and the current label result is saved and the segmentation label of the unlabeled image is transferred by right clicking with a mouse, for example, the "volume" character (the last character in the 5 th column from right to left) shown in the image label display area 990 in fig. 12 can be segmented and labeled manually.

FIG. 13 is a schematic diagram of the operation of a graphical user interface of an identify label submodule according to another embodiment of the invention.

The main functions of the identification tag submodule are explained in detail below with reference to fig. 13.

Fig. 13 shows a GUI of the recognition and labeling submodule for ancient book text recognition, and the main functions of the recognition and labeling submodule include the following aspects: the system loads the first image which is not identified and labeled by clicking an identification label button; performing automatic layout analysis based on the labeling results of the detection boxes to generate text sequence and row-column distribution information; copying the detection frame area with the sequence number of 1 to an 'identification' panel small picture area; if the label is the 0 th round label and no pre-recognition process exists, manual input (such as a pinyin input method) needs to be carried out on the current character, and the label of the next character is automatically entered according to the carriage return; if the number 1 and the subsequent marking (or the number 0 but the pre-recognition result), the system respectively displays the pre-recognized candidate results in 10 selected text edit boxes from high to low according to the confidence level, the candidate characters can be copied into the recognition marking edit box by inputting through a keyboard of 'F1-F10' or clicking through a right mouse button, and the marking result is determined by returning and the marking of the next character is transferred; whether a pre-recognition result exists or not, clicking the inside of a certain text box in a large picture area through a mouse, selecting characters to be marked, and carrying out jumping marking; or the data can be input in the large text area in sequence, the system automatically divides lines and automatically matches the labeling result to the large image area. In any mode, each labeling area (mainly comprising two areas, namely a large graph and a large edit box) synchronously displays the labeling result; for example, if the traditional word "" (the first word in the first column from right to left) of the image annotation display area 990 is subjected to identification annotation, all the identification results of "" are displayed on the identification annotation panel 950, and the first 10 ranked identification results, such as "", "", etc., are typically displayed.

The training module 840 includes a detector training sub-module, a filter (partition) network training sub-module, and a recognizer training sub-module.

For the detector training submodule, because the detection performance of the single-stage deep neural network Yolov5 algorithm is superior, the network structure of the detector training submodule is constructed on the basis of Yolov 5. Yolov5 realizes the setting of a large receptive field in a local area by the fusion of a large number of features of different resolutions of a backbone network, so that the network can generate more accurate reasoning under the condition that characters are not clearly displayed. But performs poorly for non-uniform distribution of words (e.g., a small number of small words embedded between a group of large words). Therefore, a channel attention mechanism is added in the C3 module, so that the judgment of the resolution of large and small words in a certain area has more specific channel attention expression, and the detection result is improved.

Fig. 14 is a schematic diagram of a network structure of a filtering (partitioning) network training submodule according to another embodiment of the present invention.

The filtering (segmentation) network training sub-module is described in detail below with reference to fig. 14, and as shown in fig. 14, a text confidence calculation step based on a segmentation network is added to perform text filtering in consideration of the possibility of the presence of characters on the back of the paper, incomplete characters at the edges of the image, and other noise in the ancient book picture. The network structure adopts U2-Net, the main structure of which is shown in figure 14, and the main structure is characterized in that the U-Net structure firstly expresses the characteristics from high resolution to low resolution, then samples up to the original resolution step by step, and the same level of resolution contains characteristic fusion. Each segmentation unit is in a U-net form, in the head part, each up-sampling resolution returns to a segmentation graph, and the final segmentation result is generated through a feature fusion operation.

FIG. 15 is a flow chart of the operation of the recognizer training submodule, according to another embodiment of the present invention.

The segmentation of the segmentation module 860 is different from the text region segmentation described earlier, but for segmentation at the text pixel level (like that shown in fig. 16 (b)) although the recognition module has no direct effect on the recognition of the ancient document, segmentation of the text at the pixel level contributes to data enhancement; also, text pixel-level segmentation is useful for the needs of a particular user. The segmentation algorithm uses the detection frame information and performs OTSU local binarization on the detection frame based on the assumption that the luminance of the text pixel in the detection frame is substantially consistent, and the segmentation result shown in fig. 16 (b) can be obtained by graying and local binarization on the original image shown in fig. 16 (a).
